SAN FRANCISCO, May 22, 2013 /PRNewswire/ -- Hotwire.com®, a leading discount travel site, today announced further results from its second annual American Travel Behavior Survey, conducted online on its behalf by Harris Interactive in October 2012 among over 2,000 U.S. adults. Expanding on last year's list, the survey revealed even more well-known landmarks that a majority of Americans have never visited, including The Space Needle, Yellowstone National Park, the Gateway Arch, Hollywood Sign and Las Vegas Strip. And with the weather warming up by the minute, there's no better time for Americans take advantage of Hotwire's discounts to start crossing these sights off their wish lists at a fraction of the cost.

According to the survey results:

78% of U.S. adults indicate that they have never visited The Space Needle

73% of U.S. adults indicate that they have never visited Yellowstone

70% of U.S. adults indicate that they have never visited the Gateway Arch

69% of U.S. adults indicate that they have never visited the Hollywood Sign

45% of U.S. adults indicate that they have never visited Las Vegas Strip

"The overall number of Americans who haven't visited their country's most famous sights is simply staggering, but what's even more surprising is that more people have visited Las Vegas than the White House, which last year's study found to be overlooked by 57 percent of Americans," said Clem Bason, president of the Hotwire Group. "We want to encourage people to take more trips because pictures and videos aren't enough to capture the scale and majesty of these iconic landmarks. And with the discounted air, hotel and car prices on Hotwire, a getaway to these famous sites can be planned on a very reasonable budget."

In addition to awesome landmarks, these overlooked destinations also offer some eye-opening travel discounts. To help illustrate, sample pricing for hotel rates, along with average car rental and airfare rates, have been included for each destination below:

The Space Needle, Seattle, Washington (78 percent of U.S. adults have never visited)

If there's one thing more famous than Seattle's coffee, it's the city's iconic Space Needle – a 605-foot tall tower that defines the skyline of Downtown Seattle. Constructed in 1962 to commemorate the Seattle World's Fair, the tower was once the largest structure west of the Mississippi River. And while it may have been knocked off the top spot by newer U.S. buildings, it's still a remarkable sight. Visitors to the Space Needle can take an elevator ride to the top, where there's a restaurant and an observation deck, both with beautiful views of Downtown Seattle and Mount Rainier.

Yellowstone National Park (73 percent of U.S. adults have never visited)

Even with its status as one of the U.S.' most famous landmarks and the first national park, almost ¾ of all Americans have yet to visit Yellowstone National Park. Spanning three states, the park takes up almost 3,500 square miles and is home to mountains, canyons, lakes, rivers and hundreds of species of animals. Visitors to Yellowstone have many options when it comes to outdoor activities in this colossal destination. After a trip to the world-famous Old Faithful Geyser, which erupts about once every hour and a half, folks can kayak through the West Thumb area, or even hike through any number of the park's 1,100 miles of trails.

Gateway Arch, St. Louis, Missouri (70 percent of U.S. adults have never visited)

Standing tall at 630 feet, St. Louis' Gateway Arch is truly a modern marvel, and the tallest man-made monument in the United States. Coming up on the 50th anniversary of its completion in 1965, the arch is more than just a jaw-dropping site. As part of the Jefferson National Expansion Memorial, this towering spectacle commemorates the westward growth of the United States, and is sure to please history buffs and everyday travelers just the same.

The Hollywood Sign, Los Angeles, California (69 percent of U.S. adults have never visited)

If Los Angeles has any one iconic landmark, it's the world-famous Hollywood Sign. Featured in countless films and TV shows, the 45-foot tall letters should look and feel familiar to visitors from all over the world. But folks don't have to look at the sign from afar; with just a 40-minute hike up the Hollyridge Trail, visitors can get up close and personal with the landmark and enjoy a breathtaking view of metro Los Angeles at the same time.

With a nickname like "Sin City," it might be a little surprising that Las Vegas is the survey's least-ignored landmark to date. But it's even more surprising the think that this larger-than-life Nevada mecca still has yet to be experienced by 45 percent of Americans. A constant influx of new hotels like the luxurious Cosmopolitan and vivacious nightclubs like the Hakkasan are making this desert getaway even more attractive to visitors beyond just the usual crowd from nearby southern California.
